Path fx in neopltc disease, l femur, subs for fx w malunion

This code signifies a fracture of the left femur that occurred due to an underlying neoplastic (cancerous) process, which has subsequently healed incorrectly or incompletely, resulting in a malunion. This indicates that the patient is receiving ongoing treatment or follow-up for the improperly healed pathological fracture.

Use this code for patients presenting for follow-up care, evaluation, or treatment of a left femoral fracture caused by cancer, where the fracture has healed in an anatomically incorrect position. Documentation should clearly state "pathological fracture," "neoplastic disease," "left femur," and "malunion" during a subsequent encounter.

• Ensure documentation specifies "left femur" and not just "femur" to support laterality.
• Confirm the encounter is "subsequent" for the fracture, not the initial treatment.
• Always sequence the underlying neoplasm code first, as it is the etiology of the pathological fracture.
